While unicorn lovers around the globe may be sparkling with excitement, a top gynecologist is urging women not to try the bizarre new trend, warning it could trigger nasty STIs or even “vaginal sunburn.”

Dr. Vanessa Mackay, spokesperson for the Royal College of Obstetricians and Gynaecologists in the UK, said: “The vagina contains a delicate balance of good bacteria, which are there to protect it. If women place foreign objects inside their vagina, their risk disturbing this balance which may lead to infection, such as bacterial vaginosis or thrush, and inflammation.”

“It’s important to remember that the vagina is designed to clean itself with natural secretions (discharge).”

“Women are advised to avoid perfumed soaps, gels and antiseptics as these can affect the healthy balance of bacteria and pH levels in the vagina.”

“If women experience vaginal dryness before and during sex, they are encouraged to try using a lubricant.”

“These are liquids or gels that can be applied to the vulva, vagina or penis just before having sex to keep the vagina moist.”
